New build mastic in Bassett Green, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you are dealing with shower seals failing in the first year or two and sealant that never bonded to the surface, we can put it right, on windows & doors, bathrooms & en suites and skirting & floors alike.
If you’ve bought a new home in or near Bassett Green, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Our work is backed for twelve months.

Why it’s worth doing now in Bassett Green
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Bassett Green, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy.

- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.

What new build mastic looks like in Bassett Green
Bassett Green is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Swaythling station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Bassett Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
To keep the joints looking good and working properly:
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you’re covered
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
